Title: Camera for supervision
Inventor: KIMU HOGU
IPC: G03B11/00
Filed: 1995-06-27
Abstract: PURPOSE: To provide a camera for monitor which can exactly recognize the state of monitor object despite of the strength of beams emitted from the monitor object by controlling the level of voltage to be applied to a light attenuating member corresponding to the strength of beams sensed by photosensor. CONSTITUTION: When high output beams are emitted, the intensity of beams is sensed by a photosensor 41 and these beams are outputted with a prescribed voltage value. This voltage value is sent to an attenuation regulator 50. The attenuation regulator 50 regulates the voltage to be applied to speed glass 40 by correcting the output voltage value of photosensor 41. Based on the change of this voltage, the transmissivity of beams is regulated by rotating magnetic materials inside the speed glass 40. Thus, the intensity of beam which is received in a camera 10 is attenuated. Therefore, the camera 10 exactly recognizes the state of monitor object. Further, in operation, a photocell 42 converts beam energy to electric energy and stores it in a storage battery 60. The electric energy stored in the storage battery 60 is used as an operating power source.

Title: Semiconductor acceleration sensor and fabrication thereof
Inventor: TAKAMI KAZUAKI
IPC: H01L29/84
Filed: 1993-06-30
Abstract: PURPOSE:To enhance the thermal hysteresis characteristics by bonding the rim part of silicon sensor chip to a substrate through a ceramic adhesive when a ceramic substrate and a metal substrate are employed. CONSTITUTION:When a ceramic substrate 31 and a metal substrate 21 are employed, the rim part 24 of a silicon sensor chip 21 is bonded to a substrate 31 through a ceramic adhesive layer 30. Coefficient of thermal expansion of silicon is 2.6X10<-6>/ deg.C and that of the ceramic substrate 31, e.g. alumina, is about 4.0X10<-6>/ deg.C. Since the coefficients of thermal expansion are close each other, stress due to the difference thereof is reduced. When a spacer is provided in a region of the substrate 31 corresponding to the lower part of the mass part 23 of silicon sensor chip 21, residual force is prevented from being generated at the diaphragm part 22 due to the weight of the mass part 23.
